adelphia, in the county of Philadelphia and State of Pennsylvania,"haveinvented certain newand usefullmprovements in In 111g 18 aspeclfication. .l i Thisinvention relates to improvements in. infantsnursing devices. 7 V '1 Devices of this character in general ,use'comprise a bottle and a rubber nipple apfants NursinmDevices, ofwhichthe follow plied to the neck-thereof, and they have beenobjectionable: first, because the creation'of a partial vacuum'withinthe bottle by an in fant drawing milk therefrom through the nipple hasprevented the proper and uniform flow of milk from the bottle and hascaused milk and saliva to return to the bot' tlefroin the infants mouthcarrying bac teria and germs which rapidly multiply in the milk withinthe bottleto the detriment of the health'of'the infant; second,becausethe creation of the partial vacuum within the bottle and theconsequent prevention of the free flow of milk therefrom has caused theinfant to suck air into the stomach through openings between the nippleand the infants mouth; and, third, because milk is frequently spilledfrom the bottle throughthe nipple when the infant removes the nipplefroinits the bottle containing milk is on its side or tilted from anupright position sufficiently to permit the milk to flow to and throughthe opening in the nipple.

The ob'ect of my invention is to overcome the aforesaid objectionablecharacteristics;

and with this and related objects in view, the invention consists in thenovel construction, combination and arrangement of parts hereinafterdescribed and claimed.

In the accompanying drawings illustrating my invention,

.Figure 1 is an enlarged vertical section through a nursing deviceembodying my invention, certain parts being broken away. Figure 2 is ahorizontal section thereof, on line 22 of Fig, l. I

Figure 3" 's a sectionaldetail of one of valves, on line 3'3 of Fig. 1.Referring to the drawings, a designates a glass bottle of the typecommonly known as a nursing bottle used for nursing purposes, the samebeing provided with the usual neck the z l5flhaving the flange or 'Be'it known that LWIQLIAM R. Dunne, a f citizen of the United States,residing at Philan air open. endjthereof. Mounted'onthe neck 5 is anipple '7' which 6 around i:

is formed of rubberta id provided with an expanded, or'enlarged lowerportion 8 havring-9 being stretched around the bead 6 and j i i neck inav manner to hold 1 the nipple in .place and prevent its accidentalwithdrawal. fromtheybottle. Theupper or'freeend-of the nipple has adischarge opening therein. j

Fitted tightly within'the nipple? is a plug or .inember-lO having aflange or headll formedon the lower endthereofwhich is seated within theenl'arged'lower portion 8f of the nipple and which engages the shoulderformed'b'etween' the upper portion of the" nipple and the enlarged lowerportion 8 thereof to prevent accidental upward displacement of themember withinthe nipple.

ing a ,ringl9 form'ed on the bottom thereof,

The member 10 is provided with a passage 12 extending vertically throughthe lower,

central portion of the member 10and having its lower end incommunication with the nterior of the bottle 4'. The upper endof thepassage 12 opens laterally into a larger cavity o'r'depre'ssion 13 inone side of'the member 10. The rubber nipple 7 engages .themember 10.entirely around the same and engages: the cylindricalsurface thereof'entirely around the depression 13 and normally prevents the flow of milkorother liquid" from the bottle 1 to the freeor discharge end of thenipple when the bottle is laidon its side or tilted so tha't thecontents thereof flows to the member 10. l/Vhen' the device is innursing service, the infant may readily i draw milk or other liquid fromthe bottle 4-, the suctioncreated by the infant expanding that part ofthe rubber" nipple which; surroundsthe clebression 13in the member lOand thereby permitting -the liquid to flow from the bottle 1 to andthrough the discharge end of the nipple 7. The body of the nipple thusacts, as a valve to govern the flowof liquid through the passage12; j

'The body of the bottle 4 has an air inlet opening 14 which is. normallyclosed by a tapered plug 15 seated therein and comprising a. coremember16 and a surrounding tube 17 of rubber. The core fmember haspassage 18 extending through the outer portionthereof" and ;having itsinner end openinglaterally intoa centrally I sage 18 is: open exteriorlyof; the bottle, and
